240mm Radiator Darkflash DN-D240 Black — Water Cooling Radiator for PC Liquid Cooling Systems

Darkflash DN-D240 Black is a 240mm water cooler designed for CPU cooling in desktop PCs. The cooler combines a copper water block, an aluminum radiator and two 120 mm PWM fans with ARGB lighting to provide efficient heat removal and quiet operation. A 2.1-inch LCD on the water block displays CPU and RAM temperatures and pump speed. The unit uses IIR+EPDM tubes and a three-stage pump motor to ensure long-term reliability and stable coolant flow.

Advantages

The DN-D240 offers wide socket compatibility with Intel (115x, 1200, 1700) and AMD (AM3, AM4, AM5) platforms, making it suitable for many system builds. Copper in the water block improves thermal conductivity while the aluminum radiator provides effective heat dissipation. Dual 120 mm hydraulic-bearing fans with PWM control deliver up to 1,800 RPM and a maximum airflow of 61.7 CFM with low noise. The integrated 480x480 px LCD supports 16.7 million colors for direct monitoring of system parameters.

Suitable for

• CPU cooling in gaming and workstation desktop PCs
• Systems requiring ARGB lighting synchronization
• Builders who need compatibility with Intel and AMD sockets

How to use

Install the radiator in a compatible case slot that supports a 240 mm radiator using the supplied screws and mounting plate. Attach the water block to the CPU following the included bracket instructions for your socket (Intel or AMD) and apply the supplied DP5 thermal paste with the applicator. Connect the pump to a 4-pin PWM header for speed control and the fans to PWM headers; connect ARGB cables to a compatible 3-pin ARGB header or controller. Use the Darkflash control software to configure pump and fan curves and to view temperature readouts on the LCD.

Recommendations

Ensure proper airflow through the radiator by arranging case fans for intake or exhaust as recommended by your chassis manual. Periodically check mounting screws and cable connections and use the manufacturer software to monitor temperatures and adjust fan/pump curves for optimal balance between cooling performance and noise.
